 ## Pi Widget
 
-The widget appears above Pi's editor while tasks exist. Run `/tasks` to hide or show it for the current Pi runtime. Its header is the virtual task-tree root. Root tasks render as Roman-numeral categories, their children as numbered items, and leaf sub-items use indentation without another label. Internal task IDs remain unchanged and visible in tool output. In-progress circles rotate through `◐ ◓ ◑ ◒` on the existing one-second timer refresh; other status symbols remain still. The widget shows at most 12 task rows plus a compact count of hidden tasks, so larger plans do not crowd the editor out of an 80×24 terminal.
